Class EfCoreAggregateRepository<TEntity, TKey, TMarker>

Namespace: Savvyio.Extensions.DependencyInjection.EFCore.Domain

Assembly: Savvyio.Extensions.DependencyInjection.EFCore.Domain.dll

Provides an implementation of the EfCoreRepository<TEntity, TKey> that is optimized for Domain Driven Design.

public class EfCoreAggregateRepository<TEntity, TKey, TMarker> : EfCoreRepository<TEntity, TKey>, IAggregateRepository<TEntity, TKey, TMarker>, IAggregateRepository<TEntity, TKey>, IPersistentRepository<TEntity, TKey, TMarker>, IPersistentRepository<TEntity, TKey>, IWritableRepository<TEntity, TKey, TMarker>, IWritableRepository<TEntity, TKey>, IReadableRepository<TEntity, TKey, TMarker>, IReadableRepository<TEntity, TKey>, ISearchableRepository<TEntity, TKey, TMarker>, ISearchableRepository<TEntity, TKey>, IDeletableRepository<TEntity, TKey, TMarker>, IRepository<TEntity, TKey, TMarker>, IDependencyInjectionMarker<TMarker>, IDeletableRepository<TEntity, TKey>, IRepository<TEntity, TKey> where TEntity : class, IAggregateRoot<IDomainEvent, TKey>

Type Parameters

TEntity: The type of the entity.
TKey: The type of the key that uniquely identifies the entity.
TMarker: The type used to mark the implementation that this repository represents. Optimized for Microsoft Dependency Injection.

Examples

The DI-registered EfCoreAggregateRepository<TAggregateRoot, TKey, TContext> resolves as IAggregateRepository<TAggregateRoot, TKey> when registered via AddEfCoreAggregateRepository. The aggregate data source registered by AddEfCoreAggregateDataSource provides the context. The example registers both services and resolves the repository interface.
